Re: 2005 Tucson V6. My air conditioner works real well until I get about 75 miles into a trip, and then it produces less air, and sometimes the system shuts down, and won't turn on. The dealer can't figure it out, and wants me to leave the car so they can put 75 miles on it to see what the problem is. I think I'm giving up on it and will suffer through the heat wave. Also, when I took the car in, they said the ESC needed another reprogramming which they did. Has anybody had any experience with the stability control, and related systems?
